I subscribed to VPN for the trial period. During the subscription process, I had to enter my credit card details, but I didn't have to log in to any Avast accounts. I cannot cancel the subscription now.
In the browser settings, in the "My Subscriptions" field, I have "Avast Secure Browser Pro" and the subscription details (Period: 30 days; Subscription status: Free Trial; etc.). However, in the "Me and Avast" field, there is no logged in user.
In the "My Subscriptions" field, it offers me the option to renew, cancel or review my subscriptions, but I have to log in to my account to do it, which doesn't exist, or at least I don't know about it.
I realised that while subscribing, my wife's gmail was open in the browser, so I thought maybe Avast had taken it as an open account, but when I logged into Avast with it, I couldn't find any subscriptions. (I am signed in her account while writing this post.)
I don't know how to resolve this.
